百度地图：ajax获取点位数据后如何循环生成标注
设备的实体类：

public class Ap {        private String id;//编号        private Double longitude;//经度        private Double latitude;//纬度    //getter and setter}

public class ApQueryAction extends MapBaseAction{        private String aps;        @Override    protected String exec() throws BussinessException {        List<Ap> list = mapService.getAp();        Gson gson = new Gson();        aps = gson.toJson(list);        return SUCCESS;    }//getter and setter

//获得标示物var markerList = [];//存放标注对象的数组var markerClusterer;//聚合marker对象function showAllPoint() {//判断是否存在聚合marker对象，避免重复添加标注if(markerClusterer){markerClusterer.removeMarkers(markerList);}//将标注列表清空markerList=[];$.ajax({type: "GET",url: "getAps.do",dataType: "json",success: function(data) {var Aps = eval(data.aps);for(i = 0; i<Aps.length; i++) {var apPoint = new BMap.Point(Aps[i].longitude,Aps[i].latitude);//将新增的marker对象放入数组markerList.push(new BMap.Marker(apPoint));//如果使用map.addOverlay(markerList[i])添加大量标注的话会导致浏览器反应速度很慢//map.addOverlay(markerList[i]);}//使用聚合marker,添加大量标注时性能明显提高markerClusterer = new BMapLib.MarkerClusterer(map, {markers:markerList});}});}
